pi-blaster: Added recipe

Browse Source 
This project enables PWM on the GPIO pins you request of a Raspberry Pi.
The technique used is extremely efficient: does not use the CPU and gives
very stable pulses

Patches have been provided to build pi-blaster using autotools, and to
remove startup script dependencies on the lsb.
